Rubber is the name of an elastic (0) MATERIAL which can both stretch and It can be either from natural sources, or made in factories. Natural rubber from the white sap of some trees. To collect this sap, people have to cut the tree in a special way for the sap to slowly flow out into a small box. Rubber is used to a wide variety of things, from gloves to tyres, and without it our society could not function. Where this fantastic product came from was a secret until, in 1876, Henry Wickham got seeds from rubber trees in Brazil, and them to Asia. That helped Asia to become the producer of rubber at that time, and it is still the most important producer today.
